Earth Coat

Earth Coat is a mineral-based slurry that creates a durable, breathable finish for interior and exterior surfaces. Made from natural mineral ingredients, it develops a rich, matte texture that allows substrates to breathe while aging beautifully over time.

Earth Coat can be applied directly to untreated, unsealed mineral substrates including: brick, CMU (concrete masonry units), concrete, cement plaster, stucco, natural stone, and other absorbent masonry surfaces. We do not recommend applying to wooden surfaces. For previously painted, sealed, or treated surfaces, a compatible bonding primer is recommended before application.

Yes. Earth Coat is designed for both interior and exterior applications, making it suitable for garden walls, fireplaces, feature walls, facades, retaining walls, and other masonry surfaces.

Yes. Once fully cured, Earth Coat performs well across a range of climates, including hot and humid to freeze-thaw environments. Because it is vapor permeable, it allows moisture to escape rather than becoming trapped behind the coating, helping support the long-term performance of mineral masonry substrates.For best results, apply only when air and surface temperatures are between 41°F and 93°F (5°C–34°C), and avoid application during rain or freezing conditions while the coating is curing.

No primer is needed for most unpainted, absorbent masonry surfaces such as brick, stone, concrete, or stucco. If the surface has previously been painted, sealed, or treated, we recommend applying a mineral-compatible bonding primer before Earth Coat.

We recommend using a limestone brush for a textured and earthen finish. You may also use a roller or trowel. For more information around application, view our guide here.

Slowly add water to the dry mix, making sure to not add too much water. The consistency of the finished Earth Coat should be slightly thicker than the consistency of a paint.

Earth Coat creates a soft, mineral-rich matte finish with natural variation. It can be applied smoothly for a refined appearance or more heavily for a textured, timeworn character.

5 Gallon | 32 lbs. will cover approximately 150 to 200 sq ft in 1 coat, depending on the desired thickness, application method, and the type of substrate.

We do not recommend Earth Coat for pathways with high foot traffic. It can be used in lower-traffic areas, though more frequent reapplication may be needed over time due to wear.

Earth Coast is a long-lasting material. You can expect 5–6 years in outdoor conditions, with a longer lifespan in sheltered areas. In locations exposed to severe weather, some areas may need a refresh after two years. To reapply, add another coat over the existing finish. Before applying, make sure the surface is clean, dry, and free of dirt or debris.
